This invention relates to improvements in Vaporizers. i

One of the objects of the present invention is the provision of a device adapted to be anranged between the carburetor and a fuel inlet of an internal combustion motor, whereby to facilitate the starting of a cold engine by heating the fuel between the carburetor and the engine, so that the fuel will explode more t readily when received in'the engine, and the engine can be started more quickly than with the ordinary introduction of fuel therein.

Another object of the present invention is the provision of a vaporizing devicewherein air, water vapor, and fuel vapor are'mixed together and introduced into the manifold of the engine to provide for economizing'. of the fuel, and also to provide a comparatively smooth running motor due to the improved vaporized mixture, as it is a well understood fact that the mixing, of water vapor "with liquid fuels will create asmooth operation of a motor.

A further object of the present invention is the provision of a vaporizer which can be quickly and readily placed in position between the carburetor and the fuel inlet of a motor for causing the fuel from the carburetor to pass through aheated chamber, in: creasing vaporization of the fuel and also mixing with the fuel a moist vapor from the radiator of the motor, as well as thegasified fumes from the crank case of a motor for increasing efficiency of the fuel in the engine cylinders which will also. provide for economizing in the'us'e of the fuel. i

With the above and other objects in view,

the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out inthe claims and shown in the accompanying drawing wherein:

-Figure'1is-a vertical sectional view of my improved device with parts thereof illus- Figure 2 is a sectional view on the line 22 of Figure 1. t Referring more particularly to the drawing, 1 indicatesthemain body or housing of.

j my improved device having oneend open,

and this open end is normallyfclosed by means of a head 2 attached to the body by means of screw bolts 8 with a suitable gasket 4 arranged between the head and the body. The body 1 is provided with a horizontal 'partition 5, dividing the housing into upper and" lower chambers 6. and 7, respectively, with the lower chamber somewhat larger than the.- upper chamber, as shown in Figure l.

Extending upwardly from the body is a neck portion 8 having passageways 9 and 10, therethrough, which lead into the upper chamber 6 and passageway 9 is provided with a lateral inlet 11 at its upper end, while passageway is provided with a lateral outlet 12 arrangedupon theopposite side of the head portion 13 from the inlet 11.

The head 13 is provided with laterally disposed perforated ears 14 for attachment to the conduit leading from the carburetor to the fuel inlet of a motor. Supported within the chamber 6 is an electric heating element 15 connected up by means ofthe binding posts 16 to a source of electrical supply. It will be apparent from the foregoing thatthe gaseous fuel from the carburetor will pass into the chamberi6 throughethe inlet 11 and passage 9, and after circulating around throughthe chamber 6 and becoming heated by the element 15 will rise through the passage lO and out through the outlet 12, into the fuel conduit leading to the inlet ofthe motor. Attention is also directed tothe fact that any fuel remaining between the carburetor and the motor will havea tendency to collect within the chamber Gand as soon as the heater 15 is turned on,,this fuel will become heated before takeniinto the cylinders of the motor, thus increasingthe starting fa.

cilities of the motor. e

'Atthe lower sideofthe chamber 7, the head 2 is provided with, an inlet 16 which connects up with the exhaust from the motor,. so thatthe heated exhaust -will be carried throughchamber 7 and out the outlet 16a 95 at the opposite side of the chamber. Thisheated, exhaust will heat thepartition 5 and the heat from the partition 5 will radiate in the chamber. 6, so that thegaseous fuel passing thr u h is h m rw a w ys e. re

tained in a heated condition before being re- 1 ceived into the cylinders of an engine, thus increasing the active power of the fuel. I

The head 2 has an inlet 17 to one sideof the inlet 16" and connected to this inlet 17 is one end of a U-shaped tube 18, the Other end of the tube 18 being connected uplwith a passageway 19 leading into the chamber'6. The inlet 17 is connected up many suitable manner to the crank case, so that the gasoline andoil laden vapors from the crank case can be directed upwardly through the tube 18:.and

thence up through the passageway 19 into the chamber 6 to be mixed with the fuel being directed to themotorcylinders. 1

I Bylocating the tube 18in the chamber 7 and directing the heated exhaust through this chamber, it will'maintainthe tube 18 in 1 aheated condition sothat the gasified air from the crank case will be introduced in the chamber 6 ina heated condition so as not to cool ofi' thegaseousmixture in the chamber 6. At one side of the head 2 there is aninlet nipple 20' which connects up with a passageway 21 leadinginto chamber 6. The nipple 20 is connected in any suitable manner to the upper portion of the radiator for the motor so as to direct the water vapor rising from the heated water in the radiator, to the chamber 6, to mix the same with the fuel being taken into the engine cylinders. The passageways 19 and 21 are provided with control valves 22" and 23, respectivelyfwhereby the passage of gasified air through'passage19 can be readily controlled by the valve 22, and the passage of water vapor through the passage 21 can be controlled by the valve 23 whereby the amount of gasified air or water vapor entering chamber 6 can be regulated at the will ofthe user. I

, Arranged within chamber 7 and formed integral with the bottom of the housing 1' is a baffle 2&which directs the incoming heated exhaust upwardly toward the tube 18 and the partition 5 assuring the proper heating 'ofthe'se two members. In the operation of this device, the head l3'is placed in the fuel intake conduit of the motor and positioned between the carburetor and the intake manifold of a motor. The fuel from the carburetor will enter chamber 6 through the passage 9 and in the event'of first starting the motor, the electric heating element 15 is used for thoroughly heating the gaseous fuel before the same passes into the engine cylinder. After the engi'ne has become heated so that it runs smoothly, the heating element can be turned off as the heated air from the exhaust of the engine will supply sufficient heat'to keepthe chamber 6 in a heated condition. It

will also be'noted that the gasified air from the crankcase and the water vapor from the radiator will enter chamber 6 shortly-after the motor has been started and as soonas the same'becomes heated, as the air in the crank case will'be stirred up upon movement of the motor to cause this gasified air to rise upwardly and pass through tube 18, and through passage 19into chamber 6 where it will be mixed with the gaseous fuel passing through this chamber. 7

It will be notedthat the g'asified airfrom the crank case is thoroughly heated before it enters chamber 6 to be mixed with the gaseous fuel, and the water'vapor from the radiator is directed into chamber 6 from the radiator without any unnecessary circula-' tion as this vapor is ordinarily in a heated condition and will readily mix with the heated gaseous fuel in the chamber 6;

It is believed from the foregoing th atI have provided a very simple and inexpensive device which can be introduced into the fuel tion to the maximum amount of power which canbe obtained from the fuel by mixing with line of a motor whereby the fuel entering it thegasified air from the crank case and the water vapor from the radiator. I

It will be noted in Figures 1 and 2 that the inlet 11 and outlet '12 are separated by means of a transverse partition 25, and the head has 7 a Closure wall 26 opposite the inlet 11 and a closure wall 27 is arranged opposite the outlet 12, so as to provide a positive separation ofthe outlet and inlet. I i 7 While I have shown and described the preferred embodiment of my invention, it will be apparent from the foregoing that slight changes maybe made in the construction io's when putting the invention into practice without departing from the spirit of the same or the scope of the appended claims.
